Demographic, clinical and laboratory characteristics of rapidly progressive glomerulonephritis in Turkey: Turkish Society of Nephrology-Glomerular Diseases (TSN-GOLD) Working Group.

BACKGROUND: In our study, diagnostic and demographic characteristics of patients diagnosed with RPGN by biopsy, clinical and laboratory findings in our country were investigated. METHODS: Data were obtained from the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) Working Group database. Demographic characteristics, indications for biopsy, diagnosis of the glomerular diseases, comorbidities, laboratory and biopsy findings of all patients were recorded. According to their types, RPGN patients were classified as type 1 (anti-GBM related), type 2 (immuncomplex related) and type 3 (pauci-immune). RESULTS: Of 3875 patients, 200 patients with RPGN (mean age 47.9 ± 16.7 years) were included in the study which constitutes 5.2% of the total glomerulonephritis database. Renal biopsy was performed in 147 (73.5%) patients due to nephritic syndrome. ANCA positivity was found in 121 (60.5%) patients. Type 1 RPGN was detected in 11 (5.5%), type 2 RPGN in 42 (21%) and type 3 RPGN in 147 (73.5%) patients. Median serum creatinine was 3.4 (1.9-5.7) mg/dl, glomerular filtration rate was 18 (10-37) ml/min/1.73m2 and proteinuria 2100 (1229-3526) mg/day. The number of crescentic glomeruli ratio was ratio 52.7%. It was observed that urea and creatinine increased and calcium and hemoglobin decreased with increasing crescentic glomerular ratio. CONCLUSIONS: Our data are generally compatible with the literature. Advanced chronic histopathological findings were prominent in the biopsy of 21 patients. Early biopsy should be performed to confirm the diagnosis of RPGN and to avoid unnecessary intensive immunosuppressive therapy. In addition to the treatments applied, detailed data, including patient and renal survival, are needed.

Intravascular lymphoma presenting with paraneoplastic syndrome.

Intravascular lymphomatosis (IVL) is a rare type of B-cell non-Hodgkin lymphoma (BCNHL), which can mimic many other diseases. Fever, neurological symptoms, and skin findings are the most frequent clinical findings. Intravascular lymphomatosis may be associated with genetic factors and infection with human immunodeficiency virus (HIV), human herpesvirus 8 (HHV-8), human T-lymphotropic virus 1 (HTLV1), Epstein-Barr virus (EBV), and hepatitis B virus (HBV). A 50-year-old man was hospitalized with recalcitrant hyponatremia of unknown cause. He had also telangiectatic, indurated, slightly erythematous plaques on his trunk for the last 10 days. His past medical history was unremarkable, although he was a carrier of hepatitis B. Multiple skin biopsies were performed and were considered to be diagnostic of IVL. The hyponatremia was unresponsive to water restriction and hypertonic solution support but it resolved with B cell directed chemotherapy. A final diagnosis was made as syndrome of inappropriate antidiuretic hormone (SIADH) in the setting of IVL. This case had a relatively early diagnosis with just 10-days of skin lesions. Intravascular lymphomatosis is a very rare disease and is usually difficult to diagnose. An even more uncommon presentation is IVL complicated by a paraneoplastic syndrome. There are prior reported cases of SIADH in the setting of IVL. However, this case underscores the importance of evaluating patients with SIADH for potential IVL.

A life-saving therapy in Class I HELLP syndrome: Therapeutic plasma exchange.

HELLP syndrome, which can affect multiple organ systems and cause maternal and fetal mortality, is a serious complication of pregnancy characterized by microangiopathic hemolytic anemia, elevation of liver enzymes, and thrombocytopenia. Delivering the infant usually suffices for the treatment of this syndrome. In cases with Class I HELLP syndrome, however, the clinical picture may rapidly deteriorate despite delivery. In this paper we presented the outcomes with the use of therapeutic plasma exchange in cases with class I HELLP syndrome. This study included 21 patients diagnosed with the Class I HELLP syndrome at Inonu University Faculty of Medicine, Department of Hematology between 2011 and 2014. A central venous catheter was placed and plasma exchange therapy was begun in patients unresponsive to delivery, steroid, and supportive therapy (blood and blood products, antihypertensive therapy, intravenous fluid administration, and antibiotics) within 24 hours after the diagnosis of Class I HELLP syndrome according to the Mississippi Criteria. All patients underwent therapeutic plasma exchange for three sessions each with a 1:1 volume. Hemogram and biochemical parameters of the patients were evaluated before and after the procedure. According to results, there was a statistically significant decrease in total bilirubin, LDH, AST, and ALT levels whereas a significant increase in platelet count was observed. Hemoglobin levels were increased, although this increase was not statistically significant. HELLP syndrome is primarily treated with the delivery of infant; however, some cases may show disease progression despite completion of delivery. As a potential cause of both maternal and fetal mortality, HELLP syndrome condition should be aggressively treated. Therapeutic plasma exchange is one of the available treatment options. Our study has found that postpartum use of plasma exchange therapy within 24 hours is an efficient and lifesaving treatment choice in Class I HELLP syndrome.

Demographic, clinical and laboratory characteristics of adult-onset minimal change disease in Turkey: Turkish Society of Nephrology-Glomerular Diseases (TSN-GOLD) Working Group.

PURPOSE: In our study, diagnostic and demographic characteristics of patients diagnosed with minimal change disease (MCD) by biopsy, clinical and laboratory findings in our country were investigated. METHODS: Data were obtained from the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) Working Group database. Demographic characteristics, indications for biopsy, diagnosis of the glomerular diseases, comorbidities, laboratory and biopsy findings of all patients were recorded. The data presented are cross-sectional and includes application data for the biopsy period. RESULTS: Of 3875 patients, 233 patients with MCD (median age 35.0 years) were included in the study, which constitutes 6.0% of the total glomerulonephritis database. Renal biopsy was performed in 196 (84.1%) patients due to nephrotic syndrome. Median serum creatinine was 0.7 (0.6-1.0) mg/dl, mean eGFR was 104 ± 33 ml/min/1.73 m2 and median proteinuria 6000 mg/day. The number of patients under the age of 40 years was 139 (59.7%) (Group A), and the number of patients aged 40 years and over was 94 (40.3%) (Group B). Compared to Group A, global sclerotic glomeruli (24 vs. 43, p < 0.001) interstitial inflammation (15 vs. 34, p < 0.001), interstitial fibrosis (20 vs. 31, p = 0.001, vascular changes (10 vs. 25, p < 0.001) and tubular atrophy (18 vs. 30, p < 0.001) were found to be significantly higher in Group B. There was no difference in immunofluorescent staining properties between the two groups. CONCLUSION: Our data are generally compatible with the literature. Chronic histopathological changes were more common in patients aged 40 years and older than younger patients. Studies investigating the effects of these different features on renal survival are needed.

Effect of neuro-linguistic programming on COVID-19 fear in kidney transplant patients: A randomized controlled study.

This study was conducted experimentally to evaluate the effect of neuro-linguistic programming (NLP) on fear of COVID-19 in kidney transplant patients. The study was carried out between June 2021 and October 2021. The Personal Information Form and COVID-19 Fear Scale (FCV-19S) were used to collect data. The obtained data obtained were evaluated using the SPSS 25 software. NLP was found to reduce the fear of COVID-19 in kidney transplant patients. Clinical nurses can use NLP techniques to support patients with fear in similar patient groups. Patients can be provided with access to training programs where they can learn NLP techniques.
